July 23 Cwlly. Continuation of page 75. Dunbar's notes
Dunbar's notes are as follows: "Beginning at the north eastern response along the R.R. beneath the slate quarry. [The section is ascending]
75 feet greenish-black shale
60 feet greenish-black shale like that below interbedded with beds of conglomerate, black lias. Of these the lower bed is about 6 feet thick. There may be other beds just above or not exactly repeated by the faulting and shearing of the shales. The fossils are distinctly flat ones and surrounded in the cliffs.
310 feet shale, mostly greenish and sandy with several feet of redish and slaty at the top. Much weathered. Dip varies from 20 to 30, average 30 degrees.
80 feet grey micaceous and heavy bedded siliceous sandstone (best exposed above the slate quarry where its heels off the cliff as thick as brick cars). It is a coarse grained and argillace with a few grains of quartz and many grains of white feldspar. In places, the grains are as large as small peas.
90 feet greenish grey shales, much weathered.
190 feet red slate (being quarried for roofing slates).
53 feet greenish grey shaly sandstone.
130 feet greenish grey, interbedded sandy shale
240 feet red slate. Dip 35-N. 60-W.
46 feet blackish, sandy shale and sandstone
80 feet red shales.
"Furthermore on the exploration is not continuous but the dip continues in the same direction in all of the explorations seen and the material seems to be mostly greenish black shale, much weathered. There is an exposure of these 75 yards west of that above, and again about 700 yards further east where it is more exposed
